APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Monday March 5, 2007 (MJD 54165) ---=== OBSERVING TEAM ===--- Howard Brewington Dan Oravetz Suvrath Mahadevan (UF) Scott Fleming (UF) Audrey Simmons ---=== OBSERVING PLAN ===--- ET Science! ---=== OBSERVING SUMMARY ===--- Clouds for the first few hours. After they cleared we enjoyed exceptional seeing. Took 8 exposures. Observed 5 different ET plates. We had a rotator abort that was not due to the ET fiber cable contacting the telescope (which was the cause for the rotator abort two nights ago). The 45-degree fiducial is still being missed on the slew in altitude to the zenith. Dust count was between 2000 and 2500 for approximately six hours while we were open. Optics probably need to be checked and possibly CO2-cleaned. ---=== OBSERVING LOG ===--- Afternoon: --------- The past few nights the 45-degree fiducial in altitude has been missed while slewing towards the zenith. Afternoon checkout went smoothly Night: ----- Clouds. 04:56Z - Cleared up. Started with Cartridge 9, plate E8017. GSOGTF One 50-minute exposure with the iodine cell in place (data). 05:59Z - Cartridge 3, plate E8024. GSOGTF Two 50-minute expsoures with the iodine cell in place (2Xdata). 08:00Z - Cartridge 1, plate E8026. GSOGTF One 50-minute exposure with the iodine cell in place (data). 09:02Z - Cartridge 8, plate E8021. Needed an fk5. One 50-minute exposure with the iodine cell in place (data). 09:58Z - Rotator abort when slewing from Cartridge 8 to the instrument change position. There was no indication of the ET fiber contacting the telescope to cause the abort. The abort happened when telescope was at 121=az, 90=alt and 251=rota, so the ET fibers were hanging straight down. 10:05Z - Cartridge 7, plate E8022. GSOGTF One 50-minute exposure with the iodine cell in place (data). 11:07Z - Cartridge 1, plate E8026. GSOGTF One 50-minute exposure with the iodine cell in place (data). One 30-minute exposure with the iodine cell in place (data). ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame ------------------------------------------------------------------------- ---=== IMAGING RUN DETAILS ===--- ---=== SKIPPY RESULTS ===--- Run Frame nFrames stars muErr muRms nuErr nuRms rot az el --------------------------------------------------------------------------- ---=== LTMATCH RESULTS ===--- Run Field nFields alt az nGood rowMean rowSig colMean colSig rot ------------------------------------------------------------------------ ---=== SPECTROSCOPY DATA SUMMARY ===--- Summary Checked (y/n): QA Procedures Done (y/n): UT Exp Time flavor comment (S/N)^2 totals ========================================== b1 r1 b2 r2 ----- sequence 43234, plate -9999 ------- 22:50 43234 0.0 bias 22:54 43235 0.0 bias ---=== TELESCOPE OFFSETS AND SCALE I ===--- Time Instrument Az Alt Rot Scale pos offset pos offset pos offset ------------------------------------------------------------------------------ 05:03Z 9 8017 -40.85 0.0013 55.90 -0.0015 146.46 -0.0094 1.000070 06:11Z 3 8024 7.68 0.0013 75.28 -0.0015 186.77 -0.0094 1.000100 08:06Z 1 8026 147.76 0.0017 62.99 -0.0011 -49.22 -0.0158 1.000050 09:05Z 8 8021 94.98 -0.0008 50.79 0.0007 251.06 -0.0126 1.000100 10:10Z 7 8022 111.18 0.0002 59.55 0.0009 -91.01 -0.0162 1.000100 11:11Z 1 8026 210.57 -0.0006 63.79 -0.0018 46.10 -0.0198 1.000010 ---=== TELESCOPE OFFSETS AND SCALE II ===--- ---=== FOCUS LOG ===--- setmir piston Temp Wind Time Inst scale M1 M2 Foc Az Alt (C) MPH Dir filt fwhm ------------------------------------------------------------------------------ 05:03Z 9 8017 1.00007 -691 741 150 -41 55.9 2.0 7 167 ---- 1.5 06:10Z 3 8024 1.00010 -988 456 150 8 75.3 0.7 2 131 ---- 1.0 08:06Z 1 8026 1.00005 -494 837 100 148 63.0 0.0 3 251 ---- 1.4 09:05Z 8 8021 1.00010 -988 496 135 95 50.8 -0.1 2 227 ---- 1.5 10:10Z 7 8022 1.00010 -988 411 75 111 59.4 -0.2 4 262 ---- 1.2 11:11Z 1 8026 1.00001 -99 1122 60 211 63.8 -0.5 3 277 ---- 1.2 ---=== WEATHER LOG ===--- Wind Time Temp F Dewp F MPH Direction Dust DIMM Sky 21:47Z 43 4 1 231 (SW) 412 - 22:19Z 41 3 5 191 (S) 393 - 22:51Z 40 2 1 266 (W) 392 - 23:23Z 39 -4 4 101 (E) 416 - 23:56Z 38 -12 3 76 (ENE) 424 - 00:24Z 39 -19 6 118 (ESE) 318 - 00:56Z 36 -8 6 122 (ESE) 469 - 01:28Z 33 -1 6 114 (ESE) 566 - 02:00Z 35 -1 3 131 (SE) 679 - 02:32Z 36 -4 3 214 (SW) 740 - 03:04Z 35 -1 3 192 (SSW) 1041 - 03:37Z 34 0 6 177 (S) 1124 - 04:09Z 34 0 6 165 (SSE) 1104 - 04:41Z 34 0 3 145 (SE) 1151 - 05:12Z 33 2 2 115 (ESE) 1209 - 05:44Z 34 1 5 190 (S) 1488 - 06:14Z 32 2 5 200 (SSW) 1749 - 06:45Z 32 3 3 206 (SSW) 1948 - 07:18Z 32 3 3 220 (SW) 1975 - 07:48Z 31 3 3 214 (SW) 1935 - 08:21Z 31 3 2 299 (WNW) 2008 - 08:53Z 31 3 7 250 (WSW) 1967 - 09:26Z 31 4 3 276 (W) 2244 - 09:58Z 31 4 4 269 (W) 2168 - 10:31Z 31 4 4 264 (W) 2416 - 11:01Z 31 5 3 272 (W) 2435 - 11:33Z 32 4 3 284 (WNW) 2433 - 12:06Z 31 4 1 63 (ENE) 2260 - 12:38Z 31 4 4 10 (N) 2253 - ---=== TELESCOPE STATUS ===--- 23:53Z - Began ventilation.
